[Luke]

A source for additional information on, not only OBDII systems, but detailed explanation of the various sub systems. Other subjects also cover the OBDI systems.

This site is for ODBII Technical Lbrary, however, it covers also full discussions, indirectly, of the OBDI systems as well.

The sub-sections I found very informative were:

Introduction to Emissions Systems,
Introduction to Engine Management systems.
What the Home Mechanic Needs to Know about O2 Sensors

What a library of information.....
